This happens to me as well. I fix it by putting the vehicle in neutral and pushing it either forward or backwards about a foot. Place back in park and it starts up. I have never checked codes.

look for the cover on your console that is small enough to insert sa screwdriver and gently pop it open . looking it with a small light and you will see a release that will free the shifter it wont fix the problem but it will allow you to move it into park
